The introductory line will feature Mickey Mouse, Minnie Mouse and Winnie the Pooh.
"Motherhood Maternity is excited about our collaboration with Disney," said Emilia Fabricant, president of Destination Maternity Corporation.
"We are thrilled to offer our customers sleepwear, knit tops and accessories featuring these beloved Disney characters."
Stephen Teglas, vice president and general manager of Fashion & Home North America at Disney Consumer Products added:
"This collaboration gives mom the opportunity to celebrate motherhood before her baby is born by wearing images of the nostalgic Disney characters that she fondly remembers from her own childhood.
"This is also the first time Disney is working with a maternity expert to bring quality products to expecting moms and Disney fans."
The range will launch in August and will include knit tees, sleepwear, plush toys and infant onesies from $12.98 to $34.98 in all Motherhood Maternity and Destination Maternity stores and online at www.motherhood.com and www.destinationmaternity.com.
